IRONING-MACI-IINE.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed. February 14, 1906, Serial No. 300,978.

T all whom it may concern:

Be it known that I, WILLIAM E. ANDREE, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Ironing-Machines, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to that class of ironing machines in which there is employed a concave heated surface, usually the face of a steam chest, and a rotatable cylinder or drum impinging against such surface and carrying the articles to be ironed over it.

The object of the invention is to provide improved means for moving such cylinder or drum to and from the ironing surface; and it consists in the mechanism hereinafter described and which is illustrated in the accompanying drawings, in which- Flgure 1 shows a detail side elevation of the machine Fig. 2 is a sectional detail of the roll-tensioning evice; Fig. 3 a detail transverse vertical section of the machine; and Figs. 4, 5, and 6 are details of the mechanism for raising and lowering the rollers.

Machines of this character assume various forms,there is represented in the drawings a machine having a supporting frame 10, and provided with a plurality of cylinders or drums, as .11, 12, each cooperating with a steam chest 13. "Eachcylinder is journaled in boxes 14, 15, carried by yokes 16, 17, sup ported on standards 18, 19, rising from eccentrics 20, 21, fixed upon a shaft 22, journaled in the frame of the machine. The rotation of this shaft lowers and raises the cylinder 1 1 or 12 into and out of engagement with the ironing surface of the steam chest 13, and the cylinder is guided or held againstnnaterial lateral movement by arms or links'23, 24,

pivotally attached to its shaft and to the ame 10.

The shaft 22 is rotated by means of the shaft 25, to the end of .which a hand crank may be applied or which may be power-actuated in the manner hereinafter described. The shaft 25 is connected with the shaft 22 through the medium of a beveled pinion 26 engaglng a bevel gear 27, mounted upon a shaft 28, extending longitudinally as to the frame of them'achme, and journaled in suitable boxes attached thereto, thisshaft-carrya' worm 29, which engages a worm-wheel .limits t 30 fixed upon the shaft 22. As shown the shaft 28 may be ofsuch length, and may carry such number of Worms, that it may simultaneously actuate the lifting mechanism of all the cylinders.

In order to apply power to the lifting mechanism a gear wheel 31 is mounted loosely on the shaft 25 and is constantly driven by a pinion 32, fixed on the powershaft 33 of the machine, which carries the belt pulley 34 to which is applied the driving belt. A disk 35 is keyedupon the shaft 25 and pivotally carries a dog 36, which, by the action of a spring 37, is thrown into the path of -a pair of studs 38, 39, projecting from the disk face of the gear 31 and thereby clutching the gear to the shaft upon which it is mounted and causing the rotatlon of the latter so long as the dog remains in engagement with one of thestuds.

A sto pin 40, set in the face of the disk 35,

fie movement of the dog 36, due to the action of the spring 37. The dog 36 is disengaged from the studs 38, 39, by means of a bell-crank lever 41 one arm ofwhich may be thrown into the path of a lug 42 projecting laterally from the hub of the dog 36,

this bell-crank 41 being controlled by a hand lever 43, pivoted to the frame of the machine and connected with one arm of the bellcrank by means of a link 44. In the normal position of the lever 43 the end of one arm of the bell-crank 41 projects into the path of the lug ,42, and when engaged by it forces the dog 36 upwardly out of engagement with the stud 38 or 39, this disengaging the gear 31 from the shaft 25. I The end face of the dog 36 is curved, as shown, and the'studs 38, 39, are preferably provided with anti-friction rollers in order that this disengagement may be easily effected. To avoid shock the bell-crank 41 carries a contact rod 45, slidable in a box 46, formed on the bellcrank, within which is housed a cushioning spring 47, reactin between the inner endof the box and a shou der 48-on the rod 45. fixed on theshaft 22, supports on its. periphery a backwardly-projecting arm 50 of Adisk 49,-

the bell-crank 41, and has in its rim a series of suitably disposed notches,. as 51, '52, and

59 into which a nose 53 on thearm 50 'may fall.

.The'lifting mechanism is set'in motion by 'me'rely raising the lever, 43 sufficiently to disengage the contact rod45'frjom the lug 4 2.

studs 38,, '39, and as the gear-wheel 31 is constantly rotated there is an immediate engagement of the dog and consequent rotation of the shaft 25, thereby instantly setting in motion the shaft 22 and at once commenci the raising orlowering movement of the c 'nder. The raisin of the ,lever 43 lifts t e nose 53 of the .be crank arm 50 out of the notch of the disk 49, into which it last fell, and as-the disk rotates with the shaft 22 the lever 43 may be immediately dropped, and as the bellcrank arm 50 will nowride u on the rim of the disk 49-the bell crank wil be held out of the path of the lug 42 until the next notch, as 51, in the peri hery of the disk 49 reaches the nose 53 of t e bell-crank arm and allows the lattento fall, thereby raising the contact rod into the path of the lug 42. I The weight'of the lever 43 is sufficient to insure this action. I p

The journal boxes of the-cylinders 11 and 12 are yieldingly held to their seats within the yokes 16, a spring 554 reacting between the top'of each box andfa cap 55 carried by the yoke. If desired, a machine having a greater number of cylinders may be provided by duplicating the parts herein shown, the frame 57 of an additional section of such a machine being preferabl so placed as to form a continuation of t e frame 10. The

shaft 58 of the additional section for driving the mechanism for raising and lowering the cylinders will then most conveniently receive its motion from the shaft 25of-the firstsec- V shaft, and manuall tion through a bevel gear56 meshing with the bevel pinion 26.

I claim as my invention- 1. In an ironing machine, in combination, a" frame, an ironing plate carried by the frame a rotatable cylinder coacting with the. plate, reciprocating yokes carrying the roller, guide-arms connected with the cylinder and pivotally attached to the frame, ec-

centrics-for reciprocating the yokes, a power appliedand power-re leased clutch me'c anism connecting the power shaft with the eccentrics.

2. In an ironing machine, in combination, a concave ironing plate; a cylinder coacting therewith; ayoke supporting the cylinder; an eccentric for reciprocating the yoke; a power shaft; and a manually applied and automatically released clutch for connecting the power shaft with the eccentric,

3. In an ironing machine, in combination, a concave ironing plate; a cylinder coacting therewith; a yoke supporting the cylinder;

an eccentric,for reciprocating) the yoke; a

power shaft; a gear driven ythepower shaft and having a lateral pro'ection; a disk mounted concentrically with t e gear; a dog carried by the disk; means forthrowing the dog into the path of the gear pro'ection;- automatic means for withdrawing t e dog from such ath; and operativeconnectionbetween the isk and the eccentric.
